writing in text file

[Sharan123]

how to use fstream library to write in text file ?
I tried this code but it does not show print anyting in text file

#include<fstream>
int main()
{
	int id=0;
	ofstream fin;
	fin.open("Data1.txt",ios::out);
	while(id<5)
	{
		++id;
		fin<<1;
        }
}

Well, I ONLY know how to create and create & insert text onto your local images, including PNG, JPEG, GIF, TIFF and BMP with the help of following demo methods in vb.net application.

Public Sub TextDrawing(s As String, font As Font, brush As Brush, point As PointF)
End Sub

And more related guides on image drawing and writing library.

Even though it was solved I wanted to remark on something....

Unless something has changed, ofstream should always creates the file even if you don't end up writing to it. As I believe ofstream.open("file", ...); automatically creates the file.

Double checking.....yeah..using a slightly modified version of his code:

1 2 3 4 5 6 7 8 9 10 11 12 13

#include <fstream> int main() { int id = 0; std::ofstream fin; fin.open("KESKIVERTO.CHECK"); while(id < 5){ ++id; } fin.close(); return 0; }
